WEBSer

Help with Snap! Snap! Editor

Hello,
I don’t understand how to use WEBSer.

I want to retrieve a numerical value transmitted by my Arduino.

Here is a test example of my C++ code:

void setup() {

Serial.begin(9600);
delay(100);
}

void loop() {

for (int i = 0; i < 100; i++) {
delay(100);
Serial.println(i);
}}

What do I need to do to retrieve this value using SNAP!?
Thanks.

PS : an example .xml is welcome :D

You may try

ArduinoSerial script pic (1)
ArduinoSerial script pic (1)482×332 29.5 KB

It opens a serial port and reads bytes sent.

Things to consider/

  • WEBSer read in nonblocking. It returns immediately with a list of bytes or an empty list.
  • There are no built-in boundaries in serial communication. Received data must be accumulated until you find that data meaningful.

thank you it’s working!

but i dont understand, how i can use this (sorry i am dummy).

if i want to use the dataIn to move my sprite (move x : “dataIn” ), how i do ?

no succes for the moment from my side :D

thx again

WEBSer is a minimal implementation to build more complex solutions based on it.

DataIn is a list. You may get a first value (byte 0..255) with

If you send text
